The national language evolves according to the local conditions obtaining in a particular area.A national language is a language (or language variant, i.e. dialect) which has some connection—de facto or de jure—with a people and perhaps by extension the territory they occupy. The term is used variously. A national language may for instance represent the national identity of a nation or country. National language may alternatively be a designation given to one or more languages spoken as first languages in the territory of a country.
